摘要： A stepping motor capable of improving the degree of smoothness of the rotation of the rotor thereof is provided. According to the present invention, when the width of each of magnets (41, 42, or 44, 45) in the axial direction of the rotor (3) of the stepping motor is expressed by W0, the width of overlapping of each of sets of pole teeth 15, 16 and 25, 26 in the axial direction of the rotor 3 is expressed by W1 and the width of a space between the inner surfaces of each of outer yokes(14, 24) and each of inner yokes(13, 23) is expressed by W2, the width W0 of each of the magnets (41, 42) is so set as to satisfy the relationship of W2>W0>W1.
